Introduction
The new Ferroli Modena 32C HE high efficiency condensing combination boiler is an ideal
replacement for the earlier Ferroli Optimax 25C.
The Ferroli Modena 32C HE is smaller, weighs less, has built-in frost protection and an IP protection
rating of IPX5D. This allows direct replacement wherever the existing boiler is legitimately installed
(i.e. Kitchen, Garage, Bathroom, etc.)
Although the actual position of the pipe-work connections differ slightly, the configuration remains
the same, thereby requiring only limited pipe-work alteration.
The electrical connection remains the same, i.e. all models supplied with a factory fitted three core
fly - lead to provide a permanent live connection and all models use the same volt free contacts for
any external system controls.
The flue connection the Optimax 25 C is to the right of centre but providing that there is a minimum
clearance of 35mm to the right of the existing boiler, no alteration to the existing flue position is
necessary.
